'rnrss COFFIN-SHELL MOLD.

SPECIFICATION forming part of Letters Patent No. 480,986, dated August 16, 1892.

Application filed April 20, 1892.

To all whom t may concern:

Be it known that I, WILLIAM JOHN ANTHIS- TLE, of London, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Ooflin-Shell Molds; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure I is a perspective view of my improved mold. Fig. 2 is atop view of the mold, the lid removed; and Fig. 8 is a section on line X X, Fig. 1.

My invention has for its object to readily mold coffin-shells from cement in a plastic state, so that when molding is accomplished and the cement set the core can be diminished and the mold taken apart to release the molded form to harden and dry and permit of the mold being again used without great intervals of delay.

My invention consists in the construction and combination of parts composing the mold, as will be hereinafter described, and set forth in the claims.

A is a removable or detachable base or bottom of the mold, on which base rests the eX- terior shell or flask, consisting of longitudinal sides B B' and ends C O', and said sides and ends are connected adjustably by the ends having arms 2, which pass through slots in the sides, and said arms have slots to receive a wedge or key 4, so that by driving the wedges the sides and ends will be tightened at the joints, and when the wedges are removed or loosened the sides and ends can be loosened or separated and removed from the base A by the handles 5 5 at the respective ends.

rlhe inner core of the mold consists of a bottom D, integrally connected to the longitudinal sides E E', and said sides are connected by rods F F', which have right and left threads screwing into nuts 6, secured to the sides E E'.

G G' are the adjustable ends of the core, and said ends, respectively, form a bottom and three sides of a rectangle by flanges turned inwardly at the sides and bottom, whereby the ends G G' will telescope within the sides B B and bottom D. The ends G G' are connected by a rod 8, provided with right and left threads screwing into nuts 9,

Serial No. 429,826. (No model.)

secured to said ends, so that by turning the rod by a lever entering a hole l0 in the rod the core will be elongated or shortened, as may be desired.

` 1l is a bearing on which rod S rests for its support.

H is a guide-piece secured to the bottom D, under which guide the flange 7 slides to prevent the ends G G' rising from the said bottom D.

The sides of the ends G G' are connected by a rod 13, having right and left` threads screwing into nuts 14, secured to said sides, whereby the said sides are compressed against the sides E E' of the core to make a tight joint.

The top of the shell and core are flush when the core rests on the cement within the shell or flask, and both shell and core are covered by a lid M, having a downward iiange at the side edges to keep the lid properly in place, and said lid has on the under side a bead l5, fitting against the outside of the core to make a rabbet around the inner edge of the cofnshell to receive a rim on the cover-sections.

The lid M and base A are secured removably to the shell by clamps, consisting, preferably, of two bent and screw-tapped jaws K K', connected by a right-and1eftthreaded rod L, screwing into the tapped sections of the jaws, and the other end of the jaws is bent to seat against the lid and base, so that by turning the rods axially in one direction clamping will be effected and release obtained by reverselyr turning the rods.

I claim as my invention- 1. The combination, with the mold-liask or exterior shell, of the inner core having sides E E', provided with nuts 6 and connected by rods F F', provided with right and left threads screwing into said nuts, and the extensible ends G G', having side lianges provided with nuts 14 and connected by a rod 13, provided with right and left threads screwing into said nuts, said ends provided with a nut 9 and connected by a rod 8, provided with right and left threads screwing into said nuts to elongate, widen, and contract said core, as set forth.

2. The combination, with the shell or flask having a removable bottom A and slotted sides B B', ends C O', having arms 2, said IOO sides and ends connected by keys 4, as set forth, of the innel` core having a bottom and sides, the sides having nuts 6, connected by screw-rods F F', the ends G G', having fianges telescoping against said sides and bottom, said ends having nuts 9 and connected by a screw-rod 8, and said side Iianges having nuts 14, connected by a screw-rod 13, the lid M,

fitting upon said shell and core, and the clamps fastening said lid and base or bottom A re- 1o movably, as set forth.
